WEIGHT OF WANT: A STEPSISTER’S SLOW DESCENT INTO NEED by Lora Shin

In the heat of a quiet suburban home, two stepsisters are bound by a secret that begins with envy and ends in complete surrender.

Lily has always felt small beside her voluptuous stepsister Mia. Where Mia’s body is soft, heavy, and impossible to ignore, Lily is athletic, tight, and overlooked. But one afternoon, jealousy cracks open something far more dangerous. What starts as a confrontation in front of a mirror—hands exploring curves, comparing softness against firmness—quickly becomes an obsession neither can escape.

Drawn back again and again whenever their parents are away, Lily finds herself stripped of excuses and inhibitions. Mia is calm, confident, and utterly in control, guiding her stepsister from innocent touches to breathless, shameless pleasure. As the comparisons grow more intimate and the power shifts, Lily discovers a hunger she never knew she possessed—one that only deepens with every stolen hour.

But Mia has no intention of stopping at stolen moments. She wants more. She wants everything. And she’s already planning exactly how she’ll take it next.

A slow-burn, intensely sensual story of body worship, taboo desire, and one woman’s gradual, inevitable surrender to the stepsister who now owns her pleasure.
